Abstract
In this paper, the approximated expression of Fresnel Function is given, and that the Collins Integral for diffraction calculation can be expressed by Fresnel Function with sufficient accuracy is approved. Using this methods, in many cases the diffraction calculation could be simplified notably. Finally, the comparison of a diffraction example among the ordinary calculation, simplified calculation and experiment measurement is accomplished.
